| 中文摘要 |
| 从跨学科研究的角度，以氟化工行业为例，探讨了全氟和多氟烷基物质（PFAS）和臭氧层消耗物质（ODS）两大类新污染物的共排放问题.从生产过程上解析两类物质的共生产机制，构建其内在联系；在排放途径上分析其差异性及交叉过程，剖析在样品采集、前处理和仪器分析方面所需的技术手段和挑战.在生态环境效应方面综合评估了两类污染物在不同介质中产生的生态和人群健康风险、臭氧层破坏和全球暖化效应.进一步拓展利益相关方分析、生命周期分析和质量平衡分析的视角，为新污染物共排放的研究和管理提供建议. |
| 英文摘要 |
| Emerging pollutants have drawn global concerns under rapid urbanization and industrialization. However, research has been relatively independent on specific groups of pollutants due to the limitation of the discipline. In this study, from the perspective of interdisciplinary research, taking the fluorochemical industry as an example, two major categories of emerging pollutants, per-and polyfluoroalkyl substances (PFAS) and ozone-depleting substances (ODS), were discussed regarding their co-emission. The co-production mechanism of the two types of pollutants were discussed from the production processes to reveal their internal relationship; their differences and cross-processes in the emission routes were analyzed, as well as the technical approaches and challenges required in sample collection, pretreatment, and instrumental analysis. The eco-environmental effects, including ecological and human health risks, ozone depletion, and global warming effects caused by the two types of pollutants in different media were comprehensively summarized. We also further expanded the perspectives of stakeholder analysis, life cycle analysis, and mass balance analysis to provide suggestions for further research and management of emerging pollutant co-emissions. |
